Abstract: PROBLEM TO BE SOLVED: To make it possible to effectively and rapidly machine the position to be machined by calculating the deviation from a designed value based on the detected result of the presence or absence of a workpiece at the two detected positions, and controlling the pulse laser beam emitting position based on it, thereby controlling the machined position in response to the deformation. SOLUTION: The laser processing machine comprises a laser oscillator 10 having a laser head 11 and a laser power source 13, a machining head 12, and conveying means 21 for placing a workpiece 1 to move it in a horizontal plane. Particularly, the presence or absence of the workpiece at two positions separated by a predetermined distance is detected by detecting means 125A, 125B based on the reflected beam of the detecting beam, and corresponding detection signals are generated. The oscillation of the laser beam is controlled by control means 25 based on the signals at the machined position of the workpiece 1 responsive to the change of the distance between the two detected positions. Thus, the machined position can be rapidly machined in response to the deformation of the workpiece 1.

Title: Image rejection mixer
Inventor: AMANO SHIGERU
IPC: H03D7/18
Filed: 1993-01-26
Abstract: PURPOSE:To construct the mixer part of an image rejection mixer by a monolithic microwave integrated circuit consisting of a general-purpose circuit which suppresses the output leakage of the local oscillation signal and also reduces the dependency of frequency. CONSTITUTION:A 180 deg.C-phase shifter applying a strip line 90 is provided on one of outputs of two FET mixers 52 and 62. Thus the phase of the local oscillation signal leaked out to the output is shifted. Then both outputs are transmitted through the HPF 91 and 92 and then connected to each other via a resistance 93. Thus the leakage of the local oscillation signal is synthesized and canceled. In such a constitution, the leakage of the local oscillation signal can be suppressed to the output without affecting the necessary signals.
